Question 1198135: Suppose the mean length of stay in a chronic disease hospital of a certain type of patient is 60 days with a standard deviation of 15 days. If it is reasonable to assume a normal distribution of lengths of stay, find the probability that a randomly selected patient from this group will have a length of stay of at most 88 days.

Suppose the mean length of stay in a chronic disease hospital of a certain type of patient is 60 days
with a standard deviation of 15 days. If it is reasonable to assume a normal distribution of lengths of stay,
find the probability that a randomly selected patient from this group will have a length of stay of at most 88 days.
~~~~~~~~~~~~~~~
They want you find the area under the specified normal curve on the left of the raw mark of 88
P = normalcfd(-9999,88,60,15) = 0.969. ANSWER
Alternatively, you may use an online free of charge calculator

which, in my opinion, is much more attractive tool for such calculations.
